Answer:
5.39 N
Explanation:
Given
the string has a mass of 47.3 g and a length of 0.93 m.
mass holder (M_holder = 50.0 g) that carries a weight of 5.00x10^2 g.
g= 9.80 m/s^2
By the FBD we write
Tension in the string = (M_holder+mass of weight)×g
= [(50.0+5.00×10^2)×10^-3×9.80] N
= 5.39 N
Answer:
Time taken by the arrow to travel along to hit the ground is 0.55 seconds.
Explanation:
The only "force" acting on the "crossbow" to cause it to "hit" the ground is "gravity". There is no initial velocity downward when it shoot.
d = the displacement of the object
t = the time for which the object moved
a = acceleration of the object
= the initial velocity of the object
Given values
d = 1.5 m
t = unknown
Square root both sides
t = 0.55 s
Answer:
= 19 Ω, I = 0.105 A, V1 = 1.05 V and V2 = 0.95 V
Explanation:
The correct way to solve this type of problem is to find the current or voltage values for the equivalent resistance and from here find the other values.
For a series circuit the equivalent resistance is the sum of the resistance
= R1 + R2
= 10 +9
= 19 Ω
Let's use the equation for the voltage
V = I
I = V /
I = 2/19
I = 0.105 A
In a series circuit the current is constant, so let's use the voltage equation for each resistor
V1 = I R1
V1 = 0.105 10
V1 = 1.05 V
V2 = 0.105 9
V2 = 0.95 V
Note that the sum of this voltage is the total voltage applied.
Answer:
It is called photosynthesis.
Explanation:
Here light ray strikes to interface at an angle of 45 degree and then refracts into other medium such that it will bend towards boundary.
So here the angle of incidence will be less than the angle of refraction as light moves towards the boundary after refraction which mean it will bend away from the normal
here it can be said that medium 2 will be rarer then medium 1
So here the possible options are
1. Water
Air
2. Diamond
Air
So in above two options medium 1 is denser and medium 2 is rarer
